Anti-CaSR (A884) Antibody

The Calcium-Sensing Receptor (CaSR) is a class C G-protein-coupled receptor that governs extracellular calcium sensing, parathyroid hormone secretion, and downstream control of renal calcium reabsorption and bone turnover. Antibodies.com offers this Anti-CaSR (A884) reagent as a rabbit polyclonal primary antibody recognizing a defined region of the receptor. The unconjugated IgG preparation is supplied at 1 mg/ml in phosphate buffered saline (PBS) with 0.05% sodium azide at approximately pH 7.2, and ships in a 50 µl vial. It is validated for western blot (WB) and immunohistochemistry (IHC) workflows, and it cross-reacts with Human, Mouse, and Rat CaSR, supporting comparative studies in cell lines, primary tissues, and animal models of calcium homeostasis, parathyroid function, and GPCR signaling. Store refrigerated; protect from light; do not freeze. The unconjugated format gives laboratories flexibility to pair the antibody with HRP, biotin, or fluorescently labelled secondary reagents depending on the chosen detection chemistry. Polyclonal reactivity tolerates minor species and isoform-level differences within the targeted region, and the small 50 µl pack size reduces waste for pilot experiments and limited sample panels.
